JOSEPH IMIBRIANI, OF BROOKLYN, NEW YORIL I KNITTING Application filedApril 3, 1925, Serial No.

This invention relates to knitting machines, and has for its primaryobject to provide improved means for holding the actuating means forneedles against casual movement with respect to the jacquard roller andwith relation. to the needles, thereby insuringat all times an accuratetravel or movement-of the needles.

It is another object of the invention to. provide. a devicefor the abovepurpose which is easily applicable to the ordinary jacquard knittingmachine without necessitating any material alterations therein.

.Vith the above and other objects in View, the invention consists in theimproved knitting machine, and in theform, construction and relativearrangement of its several parts as will be hereinafter more fullydescribed, illustrated in the accompanying drawing, and subsequentlyincorporated in the subjoined claims. 7

In the accompanying drawings, I have illustrated a practical embodimentof the invention, but have shown only so much of the knitting machine asis necessary for a clear understanding of my present improvements. Inthese drawings, wherein similar reference characters designatecorresponding parts throughout the several views,

Figure l is a detail View of one of the needle actuating members; a

Fig. 2 is a sectional view through the needle bed showing the relativearrangement of a needle and its actuating member and the means forrestraining said actuating member against independent movement; I

Fig. 3 is a similar view showing a slightly modified arrangement, and

Fig. 4: is a fragmentary plan view.

In the accompanying drawings, for purposes of illustration, I have showna section of the needle bed orupon which a plurality of sliding orreciprocating needles 6 are mounted in spaced grooves or channels formedin the surface of said bed.

There is also arranged for sliding movement in each of the bed channelsand in line with the respective needles, a needle actuating member 7which at one of its ends is provided with a widened head 8 for abuttingcontact against the end of the needle 6. The shaft of each actuatingmember 7 extends beyond the needle bed 5 and is adapted to be actuatedand moved in one direction by a jacquard roller indicated at 9.

Between the needle bed 5 and the jacquard MACHINE.

roller9 there is arranged two or more spaced bars 10 extending at, rightanglesto the actuating member 7. These barsmay either be grooved at oneside thereof as shown at 11 in Fig. 2 of the drawings or they may be.providedwithopenings as at 12 in Fig. These grooves or openings receivethe. respective actuating membersli'.

Suitable means is operatively connected with the spaced bars 10 andeither manually or automatically actuated for displacing or moving saidbars in relatively opposite directions as indicated by the arrows ofFig. 4

-of the drawings. Thus, it will be evident that each bar at one side ofthe openings or grooves therein exerts pressure against one side of theactuating members 7 while the other bar exerts a counteracting pressureagainst the opposite sides of these actuating members, thus restrainingsaid actuating members against a casual or accidental sliding movementrelative to the needle bed which would permit a similar accidental orunintentional movement of the needle 6. In this manner therefore, itwill be evident that the heads 8 of the actuating members 7 are at alltimes retained in abutting contact against the ends of the respectiveneedles so that the latter can in no manner slide independently of theactuating members in the grooves of the needle bed in case of vibrationofthe machine before the needles are caught by the lock, in which eventthe needles would be brought outside of the reach of said lock.

From the foregoing description taken in connection with the accompanyingdrawings, the manner .of operation and several advantages of my presentimprovements will be clearly understood. It will be seen that I havedevised a very simple and effective means for preventing accidental orcasual shifting movement of the needles in a jacquard knitting machine,and which is of such construction that no radical changes are requiredin the ordinary jacquard apparatus. I have hereinshown an embodiment ofthe device which I have found entirely satisfactory in practical use,but it will nevertheless be understood that the same re-' sults might beobtained by means of other alternative constructions. and I therefore,reserve the privi ege of adopting all such legitimate changes in theform, construction and relative arrangement of the several parts as maybe fairly'embodied within the spirit and scope of the invention asclaimed.

I claim:

1. In comhimition with the reciprocating needles of a jacquard knittingmachine an actuating element for each needle in line therewith andabutting against one end thereof, and adapted to be operated by thejacquard roller of the machine and a guide member :tor said actuatingelements extending at right. angles to the line of movement thereof andshittahle relative thereto to subjcct said elements to a restraininginfluence to prevent their casual or loluriludinal shitting movement andthere I also prevent casual shiftingmovement of the needles from theiroperative positions.

2. In combination with the reciprocating needles of a jacquard knittingmachine, an acti"in;r element for each needle in line therewith andabutting against one end.

thereof, and adapted to be operated by the jacquard roller oi themachine, and a plurality of spaced bars extending transversely of theline of movement of said actuating elements. each of said bars havingguide means for said elements and said bars adapted for relativedisplacement transvereely oi the actuating elements and in oppositedirections to thereby subject said antuating elements to a roe-trainingintluenee to prevent their accidental longitudil'ial shitting movementand thereby also prevent casual shifting movement of the needles fromtheir operative positions.

In testimony that I claim the foregoing as my invention, I have signedmy name hereto.
